    This is a pretty good prezi explaining how to do a TOK presentation. This link also discusses how to extract a Knowledge issue out of a Real life example (stem cells), making it a TOK presentation and not a science one: http://www.toktalk.net/2009/10/31/what-are-knowledge-issues-or-problems-of-knowledge/

Is Bilingualism Really an Advantage? - The New Yorker - 1 views

TOK language human sciences social studies bias

shared by Lawrence Hrubes on 26 Jan 15 - No Cached
  • Many modern language researchers agree with that premise. Not only does speaking multiple languages help us to communicate but bilingualism (or multilingualism) may actually confer distinct advantages to the developing brain. Because a bilingual child switches between languages, the theory goes, she develops enhanced executive control, or the ability to effectively manage what are called higher cognitive processes, such as problem-solving, memory, and thought. She becomes better able to inhibit some responses, promote others, and generally emerges with a more flexible and agile mind. It’s a phenomenon that researchers call the bilingual advantage.
  • For the first half of the twentieth century, researchers actually thought that bilingualism put a child at a disadvantage, something that hurt her I.Q. and verbal development. But, in recent years, the notion of a bilingual advantage has emerged from research to the contrary, research that has seemed both far-reaching and compelling, much of it coming from the careful work of the psychologist Ellen Bialystok. For many tasks, including ones that involve working memory, bilingual speakers seem to have an edge. In a 2012 review of the evidence, Bialystok showed that bilinguals did indeed show enhanced executive control, a quality that has been linked, among other things, to better academic performance. And when it comes to qualities like sustained attention and switching between tasks effectively, bilinguals often come out ahead. It seems fairly evident then that, given a choice, you should raise your child to speak more than one language.
  • Systematically, de Bruin combed through conference abstracts from a hundred and sixty-nine conferences, between 1999 and 2012, that had to do with bilingualism and executive control. The rationale was straightforward: conferences are places where people present in-progress research. They report on studies that they are running, initial results, initial thoughts. If there were a systematic bias in the field against reporting negative results—that is, results that show no effects of bilingualism—then there should be many more findings of that sort presented at conferences than actually become published. That’s precisely what de Bruin found. At conferences, about half the presented results provided either complete or partial support for the bilingual advantage on certain tasks, while half provided partial or complete refutation. When it came to the publications that appeared after the preliminary presentation, though, the split was decidedly different. Sixty-eight per cent of the studies that demonstrated a bilingual advantage found a home in a scientific journal, compared to just twenty-nine per cent of those that found either no difference or a monolingual edge. “Our overview,” de Bruin concluded, “shows that there is a distorted image of the actual study outcomes on bilingualism, with researchers (and media) believing that the positive effect of bilingualism on nonlinguistic cognitive processes is strong and unchallenged.”

  • Like a number of up-and-coming researchers in his generation, Nosek was troubled by mounting evidence that science itself—through its systems of publication, funding, and advancement—had become biased toward generating a certain kind of finding: novel, attention grabbing, but ultimately unreliable. The incentives to produce positive results were so great, Nosek and others worried, that some scientists were simply locking their inconvenient data away.

shared by markfrankel18 on 23 Nov 13 - No Cached
  • Now we are regularly bombarded with new insights into how the unconscious guides our behavior. At the same time, neuroscience has largely debunked the idea of an autonomous self that has the final say in decisions; few science-savvy folks still believe there is a “ghost in the machine,” a little homunculus in the brain who is watching our perceptions or thinking our thoughts. Some philosophers even question whether the conscious mind plays any role in our thoughts. In short, present-day neuroscience has pulled the rug out from under the concept of “the rational man.”
  • If you are asked why you chose the violin, your answer is unlikely to be an accurate reflection of the unconscious competition that led to your choice. In effect, the decision happened to you. Your brain developed a “violin neural circuit” in the same way that fame makes some actors, musicians, and novelists superstars while others, for reasons that are never entirely clear, are relegated to obscurity.
  • Imagine that you are a juror assigned to the sentencing phase of a person convicted of first-degree murder. The defendant is a 33-year-old woman who has confessed to shooting her boyfriend in the head, then stabbing him nearly 30 times before unsuccessfully trying to decapitate him with a butcher knife. Initially she tells police she hadn’t been present, that her boyfriend had been killed by “unknown intruders.” When she can offer no evidence to substantiate her alibi, she then confesses, arguing self-defense and that her boyfriend had submitted her to prior physical and mental abuse. On a national TV news show, she predicts that no jury will find her guilty, yet after a several-month trial, you find her guilty of first-degree murder. It is now sentencing time. Your assignment is to determine whether the crime warrants the death penalty or a life sentence without parole, or a lesser sentence with the possibility of parole.

    "#*?@! %$&@*! Why do a few, select words have such power to shock and offend? With help from swearing historian Melissa Mohr, Mike Williams traces the history of taboo language from Roman times to the present day and hears how cultural taboos have shaped offensive language down the centuries. He talks to American psychologist Professor Tim Jay about why we swear and discovers that children start using profane language at a much earlier age than you might imagine. And he meets psychologist Dr Richard Stephens who persuades him to take part in two swearing experiments, one of them rather painful, with some surprising results. "

    "Arguably the biggest meta-story in science over the last few years-and one that caught me by surprise-is that much of the peer-reviewed scientific literature is rotten. A pioneer in exposing this vast problem is the Stanford statistician John Ioannidis, whose blockbuster 2005 paper in PLOS Medicine presented evidence that "most current published research findings are false." Discussing his findings in Scientific American two years ago, Ioannidis writes: "False positives and exaggerated results in peer-reviewed scientific studies have reached epidemic proportions in recent years. The problem is rampant in economics, the social sciences and even the natural sciences, but it is particularly egregious in biomedicine.""

    AP: "I think there are a large number - maybe a couple of dozen - of pretty good theistic arguments. None is conclusive, but each, or at any rate the whole bunch taken together, is about as strong as philosophical arguments ordinarily get. G.G.: Could you give an example of such an argument? AP: One presently rather popular argument: fine-tuning. Scientists tell us that there are many properties our universe displays such that if they were even slightly different from what they are in fact, life, or at least our kind of life, would not be possible. The universe seems to be fine-tuned for life."

  • Lately, Johnson draws for pleasure, but for three decades she had a happily hectic career as an illustrator, sometimes presenting clients with dozens of sketches a day. Her playful watercolors once adorned packages of Lotus software; for a program called Magellan, she created a ship whose masts were tethered to billowing diskettes. She made a popular postcard of two red parachutes tied together, forming a heart; several other cards were sold for years at MOMA’s gift shop. Johnson produced half a dozen covers for this magazine, including one, from 1985, that presented a sunny vision of an artist’s life: a loft cluttered with pastel canvases, each of them depicting a fragment of the skyline that is framed by a picture window. It’s as if the paintings were jigsaw pieces, and the city a puzzle being solved. Now Johnson is obsessed with making puzzles. Many times a day, she uses her grids as foundations for elaborate arrangements of letters on a page—word searches by way of Mondrian. For all the dedication that goes into her puzzles, however, they are confounding creations: very few are complete. She is assembling one of the world’s largest bodies of unfinished art.
  • Nicholas Turk-Browne, a cognitive neuroscientist at Princeton, entered the lab and greeted Johnson in the insistently zippy manner of a kindergarten teacher: “Lonni Sue! We’re going to put you in a kind of space machine and take pictures of your brain!” A Canadian with droopy dark-brown hair, he typically speaks with mellow precision. Though they had met some thirty times before, Johnson continued to regard him as an amiable stranger. Turk-Browne is one of a dozen scientists, at Princeton and at Johns Hopkins, who have been studying her, with Aline and Maggi’s consent. Aline told me, “When we realized the magnitude of Lonni Sue’s illness, my mother and I promised each other to turn what could be a tragedy into something which could help others.” Cognitive science has often gained crucial insights by studying people with singular brains, and Johnson is the first person with profound amnesia to be examined extensively with an fMRI. Several papers have been published about Johnson, and the researchers say that she could fuel at least a dozen more.

  • Unfortunately, Dr. Kane’s study arrives alongside a troubling new reality. His project was made possible by funding from the National Institute of Mental Health before it implemented a controversial requirement: Since 2014, in order to receive the institute’s support, clinical researchers must explicitly focus on a target such as a biomarker or neural circuit. It is hard to imagine how Dr. Kane’s study (or one like it) would get funding today, since it does not do this. In fact, psychiatry at present has yet to adequately identify any specific biomarkers or circuits for its major illnesses.

TOK language gender

shared by markfrankel18 on 06 Dec 15 - No Cached
  • When someone refers to a Hispanic person or a lesbian or someone with blue eyes or curly hair or double-jointed thumbs, it’s not unreasonable to question whether the detail is merely a rhetorical flourish of sorts or is, in the speaker’s mind, substantively relevant. Such superfluous details can often be offered as a way of reinforcing a stereotype without outright stating it. It is no surprise that we often respond to statements like “My black coworker is always late” or “That blonde student is actually quite smart” or “My gay friend is so dramatic” by asking what, exactly, the speaker is “trying to say.” We are entitled to our indignation because the language presented a very clear alternative; these traits needn’t have been mentioned at all.
  • When it comes to gender, on the other hand, the language has traditionally presented no elegant alternative. We are forced to clumsily dance around the matter, or to give in and refer to our coworkers, students and friends as “he” or “she.”
  • Instead, we ought to revert to the gender neutral “they” whenever gender is not explicitly relevant. Least of all because, if the goal is greater inclusion, limiting the use of the singular they to these cases doesn’t even have the desired effect.

  • Knowledge, then, is less a canon than a consensus in a state of constant disruption. Part of the disruption has to do with error and its correction, but another part with simple newness—outright discoveries or new modes of classification and analysis, often enabled by technology.
  • ore commonly, however, changes in scientific facts reflect the way that science is done. Mr. Arbesman describes the "Decline Effect"—the tendency of an original scientific publication to present results that seem far more compelling than those of later studies. Such a tendency has been documented in the medical literature over the past decade by John Ioannidis, a researcher at Stanford, in areas as diverse as HIV therapy, angioplasty and stroke treatment. The cause of the decline may well be a potent combination of random chance (generating an excessively impressive result) and publication bias (leading positive results to get preferentially published). If shaky claims enter the realm of science too quickly, firmer ones often meet resistance. As Mr. Arbesman notes, scientists struggle to let go of long-held beliefs, something that Daniel Kahneman has described as "theory-induced blindness." Had the Austrian medical community in the 1840s accepted the controversial conclusions of Dr. Ignaz Semmelweis that physicians were responsible for the spread of childbed fever—and heeded his hand-washing recommendations—a devastating outbreak of the disease might have been averted.

  • So-called killer robots are due to be discussed at the UN Human Rights Council, meeting in Geneva. A report presented to the meeting will call for a moratorium on their use while the ethical questions they raise are debated. The robots are machines programmed in advance to take out people or targets, which - unlike drones - operate autonomously on the battlefield. They are being developed by the US, UK and Israel, but have not yet been used. Supporters say the "lethal autonomous robots", as they are technically known, could save lives, by reducing the number of soldiers on the battlefield. But human rights groups argue they raise serious moral questions about how we wage war, reports the BBC's Imogen Foulkes in Geneva. They include: Who takes the final decision to kill? Can a robot really distinguish between a military target and civilians?

  • To say that an animal has a right not to be used as property is simply to say that we have a moral obligation to not use animals as things, even if it would benefit us to do so. With respect to domesticated animals, that means that we stop bringing them into existence altogether. We have a moral obligation to care for those right-holders we have here presently. But we have an obligation not to bring any more into existence.And this includes dogs, cats and other non-humans who serve as our ‘companions’.
  • If animals matter morally, we must recalibrate all aspects of our relationship with them. The issue we must confront is not whether our exploitation of them is ‘humane’ – with all of the concomitant tinkering with the practices of animal-use industries – but rather whether we can justify using them at all.

  • Most seriously of all, the effects of suppressing national memory could be of critical importance to Poles in coming decades, and to a global audience that has yet to fully absorb the complicated lessons of World War II. In some measure at least, how rising generations of Poles see themselves, democracy, and Europe will depend on whether they can have ready access to their country’s complicated experience in World War II. The collapse of democracy, the museum’s first theme, could hardly be more salient than it is right now. And the presentation of the conflict as a global tragedy could hardly be more instructive. The preemptive liquidation of the museum is nothing less than a violent blow to the world’s cultural heritage.

  • Building an archive has always required asking a couple of simple but thorny questions: What will we save and how? Whose stories are the most important and why? In theory, the internet already functions as a kind of archive: Any document, video or photo can in principle remain there indefinitely, available to be viewed by anyone with a connection. But in reality, things disappear constantly.
  • But there’s still a low-grade urgency to save our social media for posterity — and it’s particularly urgent in cases in which social media itself had a profound influence on historic events.
  • Social media might one day offer a dazzling, and even overwhelming, array of source material for historians. Such an abundance presents a logistical challenge (the total number of tweets ever written is nearing half a trillion) as well as an ethical one (will people get to opt out of having ephemeral thoughts entered into the historical record?). But this plethora of new media and materials may function as a totally new type of archive: a multidimensional ledger of events that academics, scholars, researchers and the general public can parse to generate a more prismatic recollection of history.
